MECHANISM FOR TOTALING THE NUMBER OF REVOLUTIONS 0F A ROTARY BODY.

To all fio/tom 'it may 00m-ern Be it known that I, Vieron ALFRED ZIP- snn, a subject of the Russian Emperor, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Mechanism for Totaling the Number of .Revolutions of a Rotary Body, of which the following is a specification.

The present invention relates to mechanism for totaling the number of revolutions made by vehicles, as automobiles or the like, and the object thereof is to provide a mechanism of great eiiiciency and very simple construction.

'lo accomplish my object, I have devised a mechanism in which the transmission of movement from the driving source or prime mover-to the indicating linger is perfected through the medium of mercury or other fluid.

My invention will be clearly understood from the accompanying` drawing, in which similar reference characters denote corresponding parts and in which- Figure 1 is a plan view of my new mechanism and Figs. 2 and 3 are details thereof.

The mechanism substantially consists of a shaft p to one end of which a worm-wheel p is fixed, having a certain number of teeth, a sleeve Q adapted to be rotatively mounted on the shaft p and having fixed to one of its ends a worm-wheel Q having one tooth more than the wheel p. A second sleeve r provided at one end with a cam shaped flange r is adapted to fit on shaft p and is connected to the latter by a pin or screw bolt r2 which engages a longitudinal recess p2 in the shaft, whereby the sleeve r will be permitted to move longitudinally on said shaft, but prevented from independently rotating thereon. The sleeve r is depressed into its lowest position by a spring s arranged between itself and a screw nut or head piece p* arranged on the opposite end of the shaft p. By the spring s the cam shaped ange will be held constantly in contact with a projection or pin Q2 extending from the outer circumference of the sleeve Specification of Letters Patent.

Serial No. 763,443.

Q, and as the latter revolves, the pin Q2, riding along' the edge of the cam shaped flange, will impart to the sleeve 1 a slight axial movement. The sleeve r is provided with a circular circumferential flange fr, which extends into the space between two teeth of a gear u which is one of a series of the totaling gears for feeding the number plates, l, 2, 8, 4 and in well known manner.

The shaft Q9 and the sleeve Q are supported in suitable bearings in such a manner, that the two worm wheels p and Q simultaneously mesh with the worm Z. lhen the wheel p makes one full revolution, the wheel Q makes a full revolution and a fraction of a revolution, owing to its additional tooth, and during that fraction of a revolution the sleeve 1 is caused to slightly rise feeding the wheel u.

Assuming that the wheel p has fifty teeth and the wheel Q fifty one teeth, then, when the wheel p has made fifty revolutions, the wheel Q will complete an additional full revolution or have made fifty one revolutions. During these fifty one revolutions the sleeve r is once lifted and dropped and its flange Q2 has fed the wheel u to an extent of one tooth, that will denote, say, one mile, and so forth.

Vhat I claim and desire to secure by Letters Patent is:

In a mechanism for totaling the number of revolutions of a rotary body, the combination with number wheels and a driven worm, of two independently movable wormgears meshing simultaneously with the latter, and of which one has one tooth more than the other, an axially movable cam acted upon by a projection on said last named gear and means on said cam to feed the number wheels as it is being displaced by said projection.

In testimony whereof I afiiX my signature in presence of two witnesses.
